Be it known that 1, JAMES S. HmeoN, e 'itizeii oi, the United States, residing at Him ter, in the county of Garfield and Territory of Uklehome, have invented certeirrnew end usefui 1m royements in Automatic i "Jeigh ers, of whroh the following is a specification. My inr eiition reietes to automatic grainweigliere end more particularly to that class by Whio grain may be weighed without checking or interfering with. its movement; and my object is to produce a machine tr this. ehe "eater which operates efficieritiy end reiiabiy.

Said scale-beam frame is fulcrumed, as at 46, on vertical hangers 47, attached at their upper ends to any suitable support. (Not shown.)

4 desi ates arms formed integral with or secured rigidly to the lower ends of hangers 4'7 and pivotall cipnnected, as at49, to the U-shaped tripame, the arms 50 of said frame being-pivoted, as at 51, to the side walls of the receptacle near the end op osite from thetrip and 'ravity-catches, the rid e portion 52' of sai frame paralleling the on walls and disposed in the vertical plane of said trip- .'locked in the positions stated, because the notch of gravity-catch 34 is in engagement with the headed fin 29, as shown most cleariyin F '7.

v Vhen the doors are in the positions described, the deflector extends downwardi" to the left from a point to the'rig'ht o flan e 4 over compartment 9 to the opposite side of the partition. Now as the g'rainfalls through opening 3 upon the deflector the latter deflects it into compartment 8, wherein it accumul'a until it over balances the poise. As t e rises with the beam the receptac: wings downward from fulcrum-point 46, :3. as a result of such downward movement the trio-frame rocks on its fulcrum 49 until its bri ge portion 52 strikes the lower end of the tapered Y to'oth 33 of trip-dog 31 and slides said dog upwardly and causes it by upward pressure on flange 40 of avity-catc'h .34 to swing said catch upwar .until its notch 39 is disengaged from the headed pin 29,- which action on ocks the hinged doors and permits the weight of the grain u on the closed door to open the same and e eat the closure of the other door, thereby rocking frames 18 and 26. As frame 26 is thusrocked while gravitycatch 34 is elevated headed pin 29 strikes the curved lower edge of gravity-catch 35 and raises the same until'said pin enters the notch 39 of said catch, when the latter drops to its original position, and thereby automati'cally locks the doors in their new position.

The rocking action of frame 26 is of course accompanied by similar action on the part of frame 18, which in turn, through the pin-andslot connection with rock-lever 14, swings the deflector to the position shownin dotted lines,

'Fig. 5, so that it shall deflect the grain'entertion of the operations above described.

In order that the upward movement of'the V trip-frame may continue after upward moye ment of the gratuity-catch,- against which said trip-frame is pressing the trip-dog, ceases, said trip-dog is mounted on the headed. pin

so as to be capable of swinging thereon.

When thus arranged, there is no possibiiity of a frictional engagement between the tripframe and trip-dog which will interfere with the operation oflthe rockrframes as soon as they arereleased by the tri ping of thegravity-catch engagin' the bee ed pin.

As the gram wil esoa e from compartment Y 8 much more rapidly t ed grain enters com partment 9 from the source of supply, the weight of the poise is sufficient immediately after the door of the complartment 8 is opened to gradually reelevate t e receptacle to its original position, and thereby lower the tri frame to its original position to permit the gravity-dog to again assume a pendent os'ition, as shown in -Fig. 2, so t 1 at it wil be ready for the next rise of the tri frame.

This automatic weigher may be use in connection with a threshing-machine or with any other suitable grain-discharging ap aratus, it being understood, of course, that t e quantity of grain passing through the receptacle may be registered in any suitable manner.

From the above description it will be a parent that I have produced an automatic grain-weigher embodying the features of'advantage enumerated as desirable and which obviously may be modified in its form, proportion, detail constructlon, and arran ement of the parts without departing from t e I principle of construction involved.

Having thus described theinvention, What I claim as new, and desire to secure by Letters Patent, is v i 1. An automatic grainweigher, comprising hangers, a scale-beam fulcrumed thereon,

a receptacle suspended from the beam, a trip- 1 frame pivoted to the receptacle and fulcrumed on the hangers, a door carried by the receptacle and closed and locked when the latter is overbalanced by the beam, and means when the beam is overbalanced by weight on the door, to be actuated by the trip-frame to unlock said door and permit the weight thereon to open it.

2. An automatlc grain-weigher, comprisr ing hangers, af scale-beam fulcrumed thereon, a receptacle suspended from the beam, a tripframe pivoted to the receptacle andfuiorumed on the hangers, a door carried by the rece tacle and closed and locked when the latteris overbalanced b the beam, means when the beam is overba anced by Weight on thedoor,

to be actuated by the trip-frame to vunlock said door and umit iho weight thereon to open it, and m ms to look the door open.
